Algorithm 2 Mean-Resource Reservation Policy

Input: Demand cector $D\left[1,\dots ,T\right]$, Contract k.    (1) $D^s\leftarrow sort\left(D\right)$;       # The mean of the hour-based demands in one day is reserved for each hour in a year.    (2) Number of reserved instances ←$mean\left(D\right(1:24\left)\right)\times T$;
